Stress and Sleepiness in the 24-h Societyogether in a well-behaved way we have a distributive block structure. We show that the orbits of the automorphism group of a distributive block structure on pairs of experimental units are precisely the sets which the combinatorial structure leads one to expect. Possible generalizations of this result are discussed.

A construction for a family of sets and its application to matroids,n applied to . then gives .. For each subset . of ., . for exactly one pair of .∈. and corresponding .∈.. When the family . is the basis collection of a matroid on . can be described simply in terms of the matroid structure. A polynomial is defined which, in this latter case, is the Tutte polynomial of the matroid.
